Given its size, it’s not too difficult to hold, with a longer, thinner design rather than a larger brick shape. The build feels solid, and our sample has withstood a few drops with no ill effects. It is heavy, but that is to be expected given the large battery.

Anker makes the 737 Power Bank simple to use, as shown by its single button and basic OLED screen. The display shows real-time information about output and input power, allowing you to track the charging progress. It also estimates the time it takes for the power bank to fully recharge or discharge, allowing you to better plan and manage your charging needs.

The screen in the advanced section will display the number of charge cycles completed by the battery, as well as its overall health, current temperature, and other useful power statistics. If you want to change whether the screen goes to sleep automatically or stays on all the time, you can do so.
